From the surname of former US Senator Rick Santorum (born 1958). After Santorum made statements comparing homosexuality to bestiality and opining that mutually consenting adults do not have a constitutional right to privacy with respect to sexual acts, US columnist Dan Savage gathered input from his readers and held a contest for definitions to "memorialize the scandal". Savage set up a website which defined the term, and helped to promote it. See Campaign for "santorum" neologism for further information.
